Chapter 0.7, Problem 2E

To determine

To evaluate: the missing measure in the right angle triangle.

Answer to Problem 2E

The length of missing measure is 24km.

Explanation of Solution

Given information:

Diagram is given in the problem.

The diagram is given in the question,

  

Applying Pythagoras theorem,

So,

  $\begin{array}{l}{\left(32km\right)}^2+{\left(\text{a }km\right)}^2={\left(40km\right)}^2\\ a^2=1600-1024\\ a^2=576\\ a=24km\end{array}$

So,

The length of missing measure is 24km.
